options
o Option 1: Making of Trickling filters
coupled with Grit Chamber
o Option 2: Making of an exclusive Septic
Tank
Option 2 is one of the best method of treatment
according to conditions of Risalpur Cantt. Design
of septic tank is recommended due to following
reasons:

deposed to soakage pit.
